I've tried to reproduce your compilation error but without success.

For using Xenomai on NIOS II processor with uClinux, you must add extra 
hardware in your SoPC design as explained in this tutorial 
(http://uuu.enseirb.fr/~kadionik/nios2-xenomai/Xenomai%20on%20NIOS%20II%20Softcore%20Processor%20Guide-v1.1.pdf).

It is OK on my Altera 1S10 board  with Xenomai v2.5.1 (see traces).

Sincerely;

Patrice
